Cressida Bonas showed off quite a bit of skin when she wore a revealing black tank top to the Art Antiques London Gala Evening in aid of Children in Crisis on Tuesday. Cressida stopped by the bash at Kensington Gardens to support her close friend Princess Eugenie, who serves as a royal patron for Children in Crisis. Eugenie was at the event with her mother, Sarah Ferguson, after attending Prince Philip's 93rd birthday party at Buckingham Palace  earlier in the day. She was joined at the birthday bash by her grandmother Queen Elizabeth II, Princess Anne, and the Duchess of Cambridge. Cressida has also been having a busy few days, as she was recently confirmed to star in Tulip Fever, a new period film that also stars Cara Delevingne, Zach Galifianakis , and Dane DeHaan.
Prince Harry and Cressida announced their breakup back in April , but, according to reports at the time, the breakup appeared to be a temporary thing. However, after Harry reportedly attempted to reconcile their relationship , the two decided to split for good because either Cressida didn't want to become a princess or because Harry thought she was "too boring,"  depending on who you ask. Either way, it doesn't look like Cressida is sitting at home sulking and is instead taking a page from Kate Middleton's book  and putting herself out there while looking her very best. Kate's efforts reportedly helped her get back together with Prince William back in 2007, but it's unclear if there is still even a sliver of hope for Cressida and Harry's romance. This is good news for single girls who have their eye on snagging Prince Harry, although they will have to follow a rigid list of rules  before the prince will ever take them seriously.
